  • Patent number: 12290692
    Abstract: Described herein are methods for use with an implantable system including at least an atrial leadless pacemaker (aLP). Also described herein are specific implementations of an aLP, as well as implantable systems including an aLP. In certain embodiments, the aLP senses a signal from which cardiac activity associated with a ventricular chamber can be detected by the aLP itself based on feature(s) of the sensed signal. The aLP monitors the sensed signal for an intrinsic or paced ventricular activation within a ventricular event monitor window. In response to the aLP detecting an intrinsic or paced ventricular activation itself from the sensed signal within the ventricular event monitor window, the aLP resets an atrial escape interval timer that is used by the aLP to time delivery of an atrial pacing pulse if an intrinsic atrial activation is not detected within an atrial escape interval.

  • Publication number: 20250001189
    Abstract: A method is provided for establishing a communication session with an implantable medical device (“IMD”). The method includes configuring an IMD and an external device to communicate with one another through a protocol that utilizes a dedicated advertisement channel. The advertisement period and the scan period of the protocol are independent of one another such that the advertisement and scan periods at least partially overlap intermittently after a number of cycles. When the external device detects one of the advertisement notices, the method includes establishing a communications link between the external device and the IMD.

  • Publication number: 20240065637
    Abstract: A medical data and diagnostics management system for processing classified electrogram (EGM) datasets includes a server system that receives transmissions of classified EGM datasets, each corresponding to an arrhythmic episode detected by an implantable medical device (IMD), and applies a machine-learning model to each classified EGM dataset, thereby determining confidence indicator(s) relating to the IMD classification for each arrhythmic episode. Based upon the confidence indicator(s), the server system generates a set of machine-adjudicated EGM datasets, assigns a ranking score to each machine-adjudicated EGM dataset, and selects for display (for clinical analysis) a subset of the machine-adjudicated EGM datasets based upon their ranking scores. The machine-adjudicated EGM datasets are also stored in a database and further processed to generate diagnostic information and/or diagnostic alerts relating to the arrhythmic episodes detected by the IMD over time.

  • Publication number: 20220313161
    Abstract: Described herein are methods, devices, and systems that enable a remote non-implantable device (RNID) to send commands to a leadless pacemaker (LP) implanted within a patient. The RNID provide commands to a local non-implantable device (LNID) over one or more communication networks, and the LNID sends the commands to a second implantable device (SID) by transmitting radio frequency (RF) communication signals, which include the commands, using an antenna of the LNID. After receiving the commands from the LNID, by receiving RF communication signals that include the commands using an antenna of the SID, the SID transmits conductive communication signals, which include the commands, using electrodes of the SID. The LP receives the commands from the SID by receiving the conductive communication signals, which include the commands, using electrodes of the LP, and the LP performs command responses based on the commands that originated from the RNID.
